Fix stream freezing and alert camera name matching

- Add auto-reconnect with exponential backoff to MSE and WebRTC streams
  when connections drop, preventing permanent freezes in grid view
- Add onDisconnect callback to Go2RTCWebRTC (connectionstate monitoring)
  and Go2RTCMSE (WebSocket close detection)
- Fix alert camera names to use Frigate names (Front_Porch, etc.)
  instead of display names which never matched MQTT events
- Disable offline WyzePanV3 camera
